科学家在Exoplanet K2-18b上发现了与生命有关的分子,但新的研究会问它们是否表明生命。 Scientists found life-linked molecules on exoplanet K2-18b, but new studies question if they indicate life.

科学家在K2-18b上检测到了分子,K2-18b是离地球生命相联的124光年以外的一个外行星。 Scientists detected molecules on K2-18b, an exoplanet 124 light-years away, that are linked to life on Earth. 然而,最近由三个独立小组进行的研究令人怀疑,表明这些分子可以没有生命而形成。 However, recent studies by three independent teams cast doubt, showing these molecules can form without life. K2-18b的可居住性评估因数据噪音和温度估计增加而复杂化,凸显了在寻找外星生命方面的挑战。 The noisy data and increased temperature estimates complicate the assessment of K2-18b's habitability, highlighting the challenges in finding extraterrestrial life.
